With the rapid development of society and the improvement of living standard, the incidence rate of rectal cancer, which is cancer from dentate line to rectum sigmoid colon junction and is one of the most common malignant tumors of digestive tract, is increased remarkably in young people. Rectal cancer is low in location and is easily diagnosed by digital rectal examination and sigmoidoscope. But the position of the pelvic cavity is deep, so the anatomical relationship is complex, the operation is not easy to be thorough, and the postoperative recurrence rate is high. The rectal cancer at the middle and lower ends is close to the anal sphincter, so that the difficulty in retaining the anus and the function of the anus during the operation is a difficult problem of the operation and is also a disease which is most controversial in the operation method.

among rectal cancers, low rectal cancer accounts for a large part of rectal cancers, when the rectal tumor is less than 5cm from the anal edge, Miles operation (abdominal-perineal combined rectal cancer radical operation) is usually required to be performed, but the operation is extremely traumatic, patients need to be flaccid, the self-esteem of the patients is seriously contused, many patients cannot receive the operation, and the operation for protecting the anus is strongly required.

Clinical work experience and related research show that the suture adding of the silk thread of the anastomotic stoma of the low rectal cancer can obviously reduce the incidence rate of the fistula, but in the process of the suture adding of the silk thread, a medical care worker needs to prop the anus triangle area with a fist to barely expose the rectal stump or the anastomotic stoma.

The sleeve 38 is simultaneously screwed to the third threaded rod 36 and the fourth threaded rod 37, and the thread direction between the third threaded rod 36 and the fourth threaded rod 37 is opposite, so that the sleeve 38 rotates to change the length of the telescopic rod 7.

Preferably, a rotating shaft 39 is fixed at the lower end of the bottom plate 2, the rotating shaft 39 is rotatably connected with the box body 8, two ends of the rotating shaft 39 penetrate through the box body 8 and are fixed with positioning wheels 40, a clamping plate 41 capable of vertically sliding is arranged below the positioning wheels 40, and the positioning wheels 40 and the clamping plate 41 are matched to form a structure for locking the rotating shaft 39.

Preferably, a plurality of positioning teeth are uniformly distributed on the outer circumference of the positioning plate, clamping grooves matched with the plurality of positioning teeth are formed in the clamping plate 41, a guide shaft 42 is fixed to the lower end of the clamping plate 41, a guide plate is fixed to the outer end of the box body 8, the lower end of the guide shaft 42 slidably penetrates through the guide plate and is arranged below the guide plate, a pressure spring 43 is sleeved on the guide shaft 42, the upper end of the pressure spring 43 is fixedly connected with the clamping plate 41, and the lower end of the pressure spring 43 is fixedly connected with the guide plate.

The quantity of guiding axle 42 is two, and the lower extreme fixedly connected with arm-tie of guiding axle 42, can relieve cardboard 41 fast and die to the card of locating wheel 40 through the pulling arm-tie, makes things convenient for the rotation of axis of rotation 39 to adjust the contained angle between bottom plate 2 and the horizontal plane.

Compared with the prior art, the invention has the following advantages: 1) the device can slide along the track on the operating table, and can be quickly fixed after sliding, so that the position of the device can be adjusted; 2) the locking of the rotating shaft 39, i.e. the fixing of the bottom plate 2, is completed by the cooperation of the positioning wheel 40 and the clamping plate 41, which is a quick adjustment, so that the included angle between the lifting head 6 and the horizontal plane can be quickly adjusted; 3) the supporting plate 3 can be vertically lifted, so that the horizontal position of the pushing head 6 is adjusted, and the supporting plate 3 can also horizontally swing, so that the included angle between the pushing head 6 and the horizontal plane is adjusted at a medium speed; 4) the included angle between the lifting head 6 and the horizontal plane is adjusted through the expansion and contraction of the expansion link 7, and the final micro-adjustment is carried out; 5) the slide bar 5 can guarantee its stability at the horizontal slip in-process, can not lead to its stability because of the increase of slide bar 5 roll-off length to guarantee to push up the effect that head 6 withstood patient's anus triangle, guarantee sutural effect, release out medical personnel's heavy work.

finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
